The installers usually detect and retain your settings, so that's definitely not by design.

If you open Help > Troubleshooting Information and click "Show Folder" you will be staring your current (uncustomized) personal settings, AKA your Firefox profile. If you click up a level, do you see any other profile folders? If so, one of those probably has your lost settings and we can discuss switching you over to that folder.

If not, do you have any backups of this part of your hard drive, or did you ever upload your data using Firefox Sync?

Problems with bookmarks and history not working properly can be caused by a corrupted places.sqlite database file.
You can check for problems with the places.sqlite database file in the Firefox Profile Folder.
